UMC Sync Cache Module 256KB (Pipeline Burst Cache, COASt)

Many mainboards, supported early pentium CPU, usually had sync cache memory chips as CPU L2 cache. This sync cache module(COASt; Cache On A Stick) is external memory module used as additional CPU L2 cache. It maximizes the perfomance of the processor while the processor is waiting for instructions or data. L2 cache is used for operating closer to the theoretical limit of the microprocessor.

‘Pipelining’ suggests that the transfers after the first transfer happen before the first transfer has arrived at the processor. ‘Pipleline burst cache’ was developed as an alternative to asynchronous cache and synchronous burst cache.
